Method Detail

createAudioUnitWithComponentDescriptionError

AUAudioUnit createAudioUnitWithComponentDescriptionError(AudioComponentDescription desc,
                                                         org.moe.natj.general.ptr.Ptr<NSError> error)

Create an instance of an extension's AUAudioUnit.

This method should create and return an instance of its audio unit.

This method will be called only once per instance of the factory.

Note that in non-ARC code, "create" methods return unretained objects (unlike "create" C functions); the implementor should return an object with reference count 1 but autoreleased.
